face of these cyber myths, we still find that there is great room for improvement. Today's internet is largely mimicking the way old mainframe computers work. Despite sufficient bandwidth resources, a large amount of information was "locked" in the central database and guarded by "security personnel". Users must rely on a Web server to do all the online work, which resembles an old-fashioned time-sharing reuse system. The site looks like an isolated

This architecture is not a real DMZ, because a single device is responsible for multiple protected areas. The exact name of this scheme is the screened subnet. Screened subnets have a serious flaw-a single attack can damage the entire network because all network segments are connected to the firewall. The advantages of the DMZ. Why deploy the DMZ?

LAN security issues are often the face of attacks from the Internet, so you must always guard against these malicious attacks, the security of your local area network computer system.

First, the introduction We envision a remote control scenario: A company that has to place such a iisweb server, which is placed 300 of miles away. The server is a broadband network, air-conditioning devices, power control devices, the combination of the three server centers. This Network Service center is both stable and affordable, but requires customers to completely remotely control the server, this control is at any time, without having to run to the console to operate the server frequentl

With the expansion of the Internet and the complexity of the network structure, the network itself has shown many problems, such as viruses, cyber attacks, spam and so on. The solution of these problems requires us to further understand the basic characteristics of the network and network behavior. However, as a subject with experimen

Reduce the time of specific packet lookup access list, reduce the burden of router CPU. It is important to note that the Access-list 100 uses the keyword "established" At the end, which is used by the Cisco router access list to allow TCP to return messages.
